Modeling, Characterization and Control of a Novel Torsional Shape Memory Alloy (SMA) Actuator
Thermally activated shape memory alloy (SMA) actuators are direct-driven and produce high power density with design versatility. However, beyond their linear actuation in spring forms there is little variety and their application in robotics is limited by the challenging characterization of the actuator. In this paper we introduce a novel low-profile torsional SMA actuator design, and its compr...
متن کاملDesign, drive and control of a novel SMA-actuated humanoid flexible gripper
An elemental SMA actuator, consisting of an elastic rod with two embedded SMA wires, is presented. The recovering wire w1, with remembered ‘U’ shape, is located along the rod’s axis. The restoring wire w2, with memorized straight shape, is located in parallel with the rod’ axis with an offset distance d1. Two strain gauges, arranged in complemental configuration and sticking to the rod, are use...
متن کاملwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
15 صفحه اولMeso-scale modeling of a forested landscape
Meso-scale models are increasingly used for estimating wind resources for wind turbine siting. In this study, we investigate how the Weather Research and Forecasting (WRF) model performs using standard model settings in two different planetary boundary layer schemes for a forested landscape and how this performance is changed when enhancing the roughness by a factor four in one of the schemes. ...
متن کاملModeling SMA actuated systems based on Bouc-Wen hysteresis model and feed-forward neural network
Despite the fact that shape-memory alloy (SMA) has several mechanical advantages as it continues being used as an actuator in engineering applications, using it still remains as a challenge since it shows both non-linear and hysteretic behavior. To improve the efficiency of SMA application, it is required to do research not only on modeling it, but also on control hysteresis behavior of these m...
